Koirala, Ishwor; Shrestha, Vivek; Park, Chul-Soon; Gao, Song; Lee, Sang-Shin; Choi, Duk-Yong


All dielectric transmissive type polarization-tuned structural multicolor pixels (MCPs) are proposed and demonstrated based on a one-dimensional hydrogenated amorphous silicon (a-Si:H) grating integrated with a silicon nitride waveguide. Both bandpass and bandstop transmission filtering characteristics in the visible regime, centered at the same wavelength, have been achieved by tailoring the structural parameters including the duty ratio of the grating and the thickness of the dielectric...[Show more]
